ITfFnPlayBack interface (ctffunc.h)
The ITfFnPlayBack interface is implemented by the Speech API (SAPI) text service. This interface is used by the TSF manager or a client (application or other text service) to control the audio data for speech input text.
Each spoken word or phrase has audio data stored with the text. This interface is used to obtain the range that covers the spoken text and to play back the audio data.
A client obtains an instance of this interface by obtaining the ITfFunctionProvider for the SAPI text service and calling ITfFunctionProvider::GetFunction with IID_ITfFnPlayBack.
